Windows 7 Search Service Corruption

After running CCleaner64 (v3.11.0.1550) 64-bit, I started getting event logs indicating that the Windows 7 Search Service could not start due to corruption. These logs did not go away upon reboot so I downloaded a Microsoft "Fix it" program to "Fix Windows Search When it Crashes or is Not Showing Results." So, I ran it and it reported that it fixed the corrupted Windows 7 Search Service. Thereafter, the logs stopped.
